HYDRAULIC GOVERNOR FOR WATER-WHEELS.

SPECIFICATION forming part of Letters Patent No. 699,142, dated May 6, 1902K.

Application ledDeoember 24, 1900l Serialy No. 40,907. (No model.)

.To all whom, t muy concern:

Beit known that I, WILLIAM J. BRIDGER, a citizen of the United States, residing at Phoenix Mills, in the county of Otsego and State 'of New York, have invented a new and useful Hydraulic Governor for Water-Wheels, of which the following is a specification.

. My invention relates to devices for governing the speed of water-wheels, and has for its object to provide an improved hydraulic governor for water-wheels in which the flow of4 water to the-wheel is regulated by means of the pressure of water, steam, air, or other fluid in a cylinder, the admission of the fluid to the cylinder being through a valve operated by a governor.

With this object in View my invention consists in the improved construction, arrangement, and combination of parts hereinafter fully described and afterward specifically pointed out in the appended claims.

In order to enable others skilled inthe art to which my invention most nearly appertains to make and use the same, I will now proceed to describe its construction and operation,

reference beiug'had to the accompanying,

drawings, forming part hereof, in which- Figure 1'- is a top plan VView of a governor constructed in accordance with my invention, the valve-governor mechanism being omitted. Fig. 2 is a viewin'elevation of oneside of the hydraulic governor, the sector and rack end being broken away. Fig. 3 is a view in elevation of the opposite side of the same parts. Fig. 4 is a View in elevation of the rack and sector end. Fig. 5 is a View of the valve and a ball-governor mechanism therefor, partly in elevation and partly'in section. Fig. 6 is a similar view on a plane at right angles to that of Fig. 4, the ball-governor mechanism except a portion of its stein being broken away. Fig. 7 is a horizontal sectional view on the 'plane indicated by the broken line 7 7 of Fig. 6 looking downward. Fig. 8 is a diagrammatic sectional View of the valve, its cylinder, -and its pipe connections.

Like numerals of referen'cemark the same parts wherever they appear in the several figures ofvthedrawings. l

Referring to the drawings by numerals, 10 indicates a metal base, upon one end of which is mounted a pressure-cylinder 11, having in ita solid piston-head (shown only in dotted lines at 12 in Figs. 1 and 3) from which pro- `jects through one head of the cylinder a piston-rod 13, carrying a rack 14 at its outer end in engagement withl a horizontal sector 15, keyed on the'gate-shaft 16 of the Water-wheel. The rack 14 'is in contact with a roller 17 on an upright shaft 18, rising from the base 10, said shaft being connected to the gate-shaft 16 by a cross-bar 19, secured by nuts 20.

21 indicates a vertical valve-cylinder mounted on the base lOby the'side of the pressure cylinderand provided with opposite ports 22 22a, 23 23e, 24 24a, and 25 25a.

26 indicates a pipe from any suitable supply of water, steam, air, or other iiuid under pressure leading to port 25, while a branch 26' therefrom leads toi port 22.

27 indicates a pipe leadingfrom port 22a to one end of the pressure-cylinder, and 27fL a' branch from said pipe, leading from port 23a.V 29 indicates a pipe leading from port a to the opposite end of the pressure-cyliu der and having a branchV 29n leading from the port 24. .Y f

28 indicates an exhaust-pipe leading to the outer air from port 23 and havingV a branch 28a leading from port 24.

Y 26b indicates a pressure-gage, and 26c a cut'- o valve in pipe 26.

In the valve-cylinder 2l is a valve 32, having lports 33 and 34 at the same distance apart vertically as the valve-cylinder ports 22 and 24 or 23 and 25, as clearly shown in the diagrammatic Fig. 8, which illustrates the valve closed andin the position itassumes when the water-wheel is running at proper speed and needs no regulating. The valve-stem is connected to the stem 35 of a ball-governor 36, driven by bevel-gearing 37 38 from a horizontal shaft 39, driven by a belt 40, c0nnecting` a pulleyvon Vshaft 39.with a pulley on a shaft driven by the machinery inf the usual manner. IThe valve-stem 41 is flattened, and at the lower end of the Aflat portion a--pin 42 is passed through a hole therein, link-bars 43 44 being pivoted at their lower ends on said pin and secured by split keys`45 or other suitable fastenings. The bar extends upward and is pivotally secured in the arms of a forked lever 46, pivoted between the jaws of a bifurcated upright fulcrum-pin 47, threaded into the plate 4S at the upper end of the valve-cylinder. The upper part of the fiat valve-stem is slotted at 49, and the flat lower end 50 of the ball-governor stem lits slidably therein, being secured by a pin 51, mounted in a casing 52, forming part of a bracket 53, secured to the valve-stem, said pin working in holes in the valve-stem and governor-stem and being normally pressed inward by a spring 54 and withdrawable against the pressure of the spring by means of a cross-handle pin 55. The casing 52 is provided with an angular slot 56, in which works a pin 57, projecting radially from pin 51, whereby the pin 51 may be locked in its withdrawn position in a well-known manner.

With the water-wheel running at proper speed and the valve in the position shown in Fig. 8, as before described, an increase of speed will cause the governor-balls to rise and carry up the stem and valve, which will bring gates 33 and 34 in line with ports 23 23 and 25 25, permitting the .Huid under pressure to How through pipe 26, ports 25 25, and pipe 29 into the pressure-cylinder 11 and move the piston-head, piston-rod, and rack 14, causing sector 15 to turn gateshaft16,cut ting oif part of the water-supply from the water-wheel and reducing its speed, the opposite end of the cylinder being exhausted at the same time through pipe 27, branch 27, ports 23 23,and pipe 28. Vhen the speed is reduced to the normal, the governor will have brought the valve back to the position of Fig. 8. Should the water-wheel run too slowly, the governor-balls will drop, bringing valve-gates 33 and 34 in line with ports 22 22 and 24 24, permitting fluid under pressure to pass through pipe 26, branch pipe 26, ports 22 22, and pipe 27 to the opposite end of the pressure-cylinder, moving its piston-rod and rack and turning sector' 15 and gate-shaft 16 in the opposite direction, opening the gate, whereby a greater supply of water will be admitted to the water-wheel until its speed is increased to the normal rate. At the same time the opposite end of the cylinder will he exhausted through pipe 29, branch 29, ports 24 24, and pipe 28. When the water-wheel is stopped, the gates 33 and 34 will be below the line of ports 23 and 25, and to start the wheel the valve is raised by means of lever 4G and link-bars 44 and 45 to bring the gates and ports in line to move the piston-rod, rack, and sector, turn the gate-shaft, and admit water to the wheel. In this operation the governor-ball stem may be released from engagement with the valve-stem by withdrawing its connecting-pin 51 and locking it by turning pin 57 in slot 5G, as before described. If, however, the pin 51 is withdrawn but not locked, its point will be pressed against the governor-stem, and as soon as the speed of the governor gets high enough to raise the stem to that point the spring will cause pin 57 to slip into place and automatically make the connection.

By means of my invention the speed of Water will be reliably and automatically regulated, and by slight alterations the hydraulic governor may be applied to regulate the running of motors of other kinds.

While I have illustrated and described what I consider to be the best means now known to me for carrying out my invention, I do not wish to be understood as restricting myself to the exact forms of constructions shown, as many slight changes therein or variations therefrom might suggest themselves to the ordinary mechanic, all of which would be clearly included within the limit and scope of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a water-motor, a pressure-cylinder, a gate-shaft operatively connected with said cylinder for regulating the water-Supply, a

valve-cylinder communicating therewith, a

longitudinally-movable valve in the valvecylinder provided with openings to form ports and havingits stem slotted longitudinally and perforated transversely of the slot, a casing secured to the stem provided with an angleslot, a spring-pressed pin within the casing in position to enter the perforation of the stem, a pin projecting through the angular slot for moving the firstmentioned pin, and the governor provided with a perforated stem within the slot of the valve-stem and adapted to be locked against longitudinal movement therein by the spring-pressed pin.

2. In a water-motor, a pressure-cylinder, a gate shaft operatively connected with said `cylinder for regulating the water-supply, a

valve-cylinder communicating therewith, a longitudinally-movable valve-stem therein provided with openings to form ports and having its stem reduced and slotted longitudinally and perforated, a bolt through one of said perforations, a link upon each end of the bolt and extending along the slotted portion, the free end of which is provided with an outwardly-extending pin, a support on the head of the valve-cylinder, an arm pivotally secured therein, one end of which is forked and engages with the pins in the ends of the links, a governor, the stem of which ts within the slotted portion of the valve-stem, and means for detachably locking said governorstem against longitudinal movement 'in the valve-stem.
